This genus is closely rcdated to IfoJocentrus, differing externally, in 

 the al)sence of the large spine at tlu' angle of the preopercle and espe- 

 cially in the very rough surface of the large scales. In this regard it 

 differs from Myrljfi'lsti'^^ which, while lacking also the preopercular 

 spine, has the scales of JLilocentrxs. IlolotracJiys {Jhun)^ another 

 genus with similarly rough scales, differs from OxtlcldltyH in having 

 the scales ver}' much smaller, about 45 in the latei'al line instead of 28, 

 as in OxflchthyK.
